So my project worked okay till now. I got this exception when I tried to start in cuba Studio:
BUILD FAILED Total time: 6.624 secs [08:21:02.493] Task 'deploy, start' failed org.gradle.api.GradleException: Unable to find SCSS file ...\myproject\modules\web\build\themes-tmp\VAADIN\themes\bin\styles.scss
And this is not the first time.
Sometimes it randomly happens. But I did not modify the VAADIN theme neither the scss files, So I am sure it is lying. Now I have a headache from it. Lots of time I had to restart my work from a backup. And it is really unpleasant.
Nowadays I found that, if I delete bin folder from here: …\myproject\modules\web\themes\ then it is build and works.
Why? What happens why it can’t build my project?
